Think he's like Billy Davies Forest, or Nigel Pearson who was at Leicester, in that they may be good at what they do but are unfortunately so wrapped up in their own views of themselves and how good they perceive themselves to that they're concentrating on the wrong things and making decisions that suit them, rather than which achieve the best outcome for their players. So yes, very knowledgeable and in Collins' case a great player, but not suited to management.
